PATENT WILLIAM M. WHITING, OF ELIZABETH, NEW JERSEY.

CORD-ALARM FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 317,905, dated May 12, 1:885.

Application filed October 28, 1884.

To @ZZ whom it may concern,.-

Be it known that I, WILLIAM M. WRITING, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain newand useful Improvements in Cord-Alarms for Grain-Binders, of which the following is a specification, reference being had to the accompanying drawings.

My improvements may be used with any grain-binder in which string is used as the binding material, and I have shown it as applied to the well-known (lhampion,77 a machine of the Appleby type.

It consists in an alarm mounted upon the machine and normally held out of action by the string o1' binding material,upon the breakage or exhaustion of which the alarm will be released and give audible notice to the driver.

In the accompanying drawings, which show so much of a grain-binder as is necessary to a proper illustration of my invention,Figure lis a rear elevation of the binding-table; and Fig. 2 an elevation, partly in section, of the under side of the binding-table, as seen from the grain side of lthe machine.

The cord-supply box A, spring-tension B, binderarm C, and knotter-head D, with its cord-holding mechanism, are properly grouped with regard to each other and the binding-table E as is usual in these machines.

As shown, the cord is led from the supplybox through the tension device B, through a guide-eye, b, through the eye of the needle or binder arm, and thence to the cord-holder in thc knotterhead, by which the end is always firmly held.

At any suitable point between the cordholder and the tension device where a constant tension is maintained on the cord, I locate a bell or any .kind of an alarm,which engages with the cord and by its tension is held out of action; but should the cord break or the supply become exhausted it immediately slackens, and permits the alarm to become active and give audible notice of the occurrence.

(No model.)

In the drawings I have shown a loose-clap per bell, F, carried by a conical spiral spring, f, the base of which is attached to the under side of the binding-table. The clapperf of the bell is provided with aloop,through which the string passes. The bell when engaged with the cord under tension is drawn up and held in the position shown by full lines; but when released from the string it falls to the position shown by dotted lines, and is swung or vibrated by the jolting of the machine over rough ground.

It has heretofore been necessary for the driver, in addition to his numerous other duties, to watch the bundles as they were formed and cast from the machine,to see that they were properly bound. Breakage of the string is Inost often the cause of failure of the machine to perform this function, and it has frequently occurred that a number of bundles would be cast unbound from the machine before the accident was discovered by the driver, who in going over rough ground or for other reasons might be too wholly otherwise occupied to be able to watch the bundling operation.

I do not wish to confine myself to the precise mechanical construction herein described, as many changes in form will readily occur to skilled persons, and may be employed to adapt the invention to the many styles of binders, that shown being the first to suggest itself and the easiest of illustration; but

What I claim, and desire to secure by Letters Patent, is-

In a grain-binder, the combination of a cordholder, a tension device, and the binding-cord held in tension thereby with an alarm engaging the cord between the tension device and cord-holder and by it restrained from action.

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM M. VVHITING.
